Augmented Appendage Robotic Machination (A.A.R.M.)

This large metallic prosthetic arm has been crafted with a psionic crystal faceted into the bicep . There are shifting plates and gears all up and down the surface of the arm which hide and conceal multiple compartments. There are multiple outlets and sockets that allow for future augmentation.

The A.A.R.M. can house a number of enhancements equal to your proficiency bonus plus your intelligence modifier. Below are the current enhancements:

• The prosthetic is a fully capable part of your body.
• +1 bonus to attack and damage with guns, pistols, rifles, muskets, shotguns, and other similar explosive based ranged weapons. (Firearms)
• The arm can hold and conceal two weapons that do not have the Heavy or Two Handed property (Inside Wrist), and one weapon with the Heavy or Two Handed property (Forearm). These weapons are stored within the arm and can be withdrawn with the Use Object item interaction.
• The arm can hold an infinite amount of ammunition for any number of firearms. This ammunition is stored in an extra dimensional space underneath the tricep. 
• The prosthetic is a magic melee weapon with which you’re proficient. It deals 1d8 force damage on a hit
